MACHINE FOR MEASURING GRAIN.

SPECIFICATION forming part of Letters Patent No. 261,210, dated July 18,1882.

Application filed March 15, 1882.

To all whom it may concern Be it known that I, TARREN It. EDGING- TON,of Waterloo, Iowa, have invented a new and useful Improvement inMachines for Measuring Grain, of which the following is a full,

clear, and exact description, reference being bad to the accompanyingdrawings, makinga part of this specification, in which Figure 1 is aperspective view of a grainmeasurer with my improvements attached. Fig.2is a vertical section through theline x x of Fig. 1. Fig. 3is asideclevatiomshowingthe registering device.

My invention has reference to devices for automatically measuring orweighing small grain as it passes from elevators or other points ofstorage to its point of destination; and it consists in the combinationof devices hereinafter described and claimed.

To enable others skilled in the art to make and use my invention, I willdescribe the exact manner in which I have carried it out.

In the drawings, A represents the frame in which revolves themeasuring-wheel B, the latter provided with any desired number ofbuckets, G, into which the grain passes to be registered or weighed. Theaxle of this wheel has its hearings in the frame A, and on one end ofthe axle is secured a block, D, provided with fingers d,correspondinginnumber to the buckets in the wheel B, for the purpose here inafterexplained.

Above the wheel B, and attached to the frame A, is the metal frame E,provided at its central point with the opening E, and having a swingingdoor, 0, for closing the opening E. The spaces between the buckets O areprovided with projecting curved springpieces F, which press against theswinging door 0 and cause the same to close automati- Cally during therevolution of the wheel and while there is no bucket beneath the openingto receive the grain. Immediately above this opening rests the spoutleading from the elevator or other reservoir.

On one end of the frame A is pivoted the bentrod G, provided with thearmsg and g. On

the long arm g is secured the adjustable weight G as a counterpoise tothe weight or measure of the grain received into the bucket G. If it beintended to measure the grain, this adjustable counterpoise is placed inposition to counterbalance a bushel or any other desired quantity to bemeasured in one bucket or, if

(N0 model.)

the grain is to be weighed, it is placed so as to counterbalance onehundred or any other desired number of pounds of grain. The short arm 9rests upon the periphery of the wheel B, and drops into the socket H ata point to arrest the movement of each bucket in turn immediately underthe opening E, and the bucket cannot move from its position withoutraising the arm 9 by means of the cam h, and this necessarily raisesalso the weight G on the long arm g.

From this description it is evident that if the weight G has beenadjusted for weighing a hundred pounds of grain, when that amount is inthe bucket O the wheel B will be partially revolved by the weight of thegrain, the counterbalance will be lifted, and the wheel will continue torotate until the next bucket passes under the o 'iening E, when theshort arm 9 will again fall into another socket Ll, and the swingingdoor he allowed to fall of its own weight and grain be admitted into thenextbucket, the descending bucket discharg ing its grain into anydesired receptacle as each bucket is passed in turn with its desiredquantity of measured grain. The axis of the wheel B, While rotating,causes one linger of the block 1) at each movement of a bucket to comein contact with a cog on the registeringwheel I and revolve it onespace, and this is repeated each time a bucket descends.

The axle of the wheel I carries a pinion, 2', which meshes into thesecond registering wheel, J,and that in turn has on its axle a pin ionwhich meshes into the large registeringwheel K. These threeindicating-wheels may be adjusted to each other in any manner de sired.Each wheel is provided with an indexfinger to point out the number ofbushels or pounds registered at any given time.

Having thus explained my invention, what I claim as new,and desire tosecure by Letters Patent, is

The wheel B, provided with the buckets O, and the cams h and sockets Hon the periphcry of the wheel, in combination with the rectaugularly-bntrod Gr, provided with the arms g g and the adjustable counterpoise G,all constructed substantially as and for the purpose set forth.
